  HTRANSFORM    hColorTransform,
  DWORD         nColors,
  DWORD         nInputChannels,
  COLORDATATYPE cdtInput,
  DWORD         cbInput,
  PVOID         pInputData,
  PBYTE         paResult
);

Parameters

hColorTransform

A handle to the specified WCS color transform.

nColors

The number of elements in the array pointed to by pInputData and paResult.

nInputChannels

The number of channels per element in the array pointed to by pInputData.

cdtInput

The input COLORDATATYPE color data type.

cbInput

The buffer size of pInputData.

pInputData

A pointer to an array of input colors. Colors in this array correspond to the color space of the source profile. The size of the buffer for this array will be the number of bytes indicated by cbInput.

paResult

A pointer to an array of nColors bytes that receives the results of the test.

Return value

If this function succeeds, the return value is TRUE.

If this function fails, the return value is FALSE. For extended error information, call GetLastError.

Remarks
